The same thing happened to my Saison I made this summer!! It continued to bubble even after 2 weeks in the secondary (with one week in primary). I gave it another week and a half before the bubbling subsided. Saison yeast definitely acts differently than most other strains I have used. But hey long attenuation is a good thing!!

Which Saison yeast did you use? I found that Wyeast 3711 tends to get done quick vs WLP 565 which also works great but takes a little longer to finish out. Both are great strains but work a little different. I usually let the 565 go for a month then bottle/keg. Pitch rate and temps are the key to a good saison. I tend to ramp up the temps into the 80s and keep them up there for most of the initial fermentation usually for a few weeks.

Another recent study found that Americans drink an average of 22 gallons of beer a year.

The Temperature Range for this one was 70 - 95 degrees. I was storing in my hot garage (liquid temps were only running in the high 70's) during hot summer days, but, it's gotten decidedly cooler the past few days. I looked into the Brew Belt, and they only said I'd get 70 - 75 degrees max (and 80 is about what my garage was running), so, I passed on purchasing it.

How else could I increase the heat w/o a temperature controlled unit of any kind? (and the follow up would have to be what kind of temperature controlled unit + device would I want in the future to get 85 / 90 degree fermentations?)

So true.
My first crack at a saison with 3724, I severely underpitched, and even though I ramped the temp up to 90, it took 8 weeks to finish and was filled with flaws (in my opinion).
My most recent attempt, I actually pitched a proper amount of yeast into well oxygenated wort at 70F. I ramped 3F per day to 90, and it was done in 2 weeks. 1.068 to 1.003. And it tastes like heaven.

Many people have reported good success with wrapping the fermentor in an electric blanket, or creating a water bath and heating that with an aquarium heater.
